Bar Code Blitz

Length: 5:05
Shown at PDC05: Yes

Lorin and Lawrence set out on a project to make bar codes appear on web pages. Techniques demonstrated include use of the new Generic Handler template in Visual Studio 2005 and the use of GDI+ to dynamically render a GIF image. The code for the bar code solution shown in the video supports two common standards: 3 of 9 for text, and 2 of 5 codes for numeric.


  • Lorin Thwaits - writer, director, producer, developer in plaid
  • Lawrence Grant - developer in maroon
  • E.W. Lloyd - "The Boss"
  • Andrew Holliday - Film crew

Tools used

  • Visual Studio 2005 April CTP

    This was my favorite video of the bunch. Funny, clever, cool, and quick. Never too fast to understand, but fast enough to keep it moving. Great job, guys!

    That is truly awesome! Cool Five minutes has never rushed by so quickly whilst watching an internet video. If only all demos were like this - fast-paced and well-scripted. Any chance Lorin and Lawrence can post the source?

    Any chance to get the source code?  I couldn't quite catch all of the index values.

    When we made this video for the PDC ShowOff event we were limited to 5 minutes total.  We had actually taken lots more footage during the original filming.  So I have now put together a longer version that includes all the content and greater bandwidth so you can actually read what the code says as it flies by.  You can download it from this link:

    For those interested in the source code, it's available for download in a .ZIP from that site.  It will do both 3 of 9 and also 2 of 5 codes.
